This application claims priority of Chinese Patent Application No. 201710184391.0 filed on Mar. 24, 2017, entitled “An allocation method and apparatus for Code Block Groups in a Transport Block”, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present invention relates to the field of electronics and communication, and in particular relates to an allocation method and apparatus for Code Block Groups in a Transport Block.

BACKGROUND

Under the circumstances of Long Time Evolution (LTE) in prior art, data is transmitted in basic units of Transport Blocks (TBs), and one TB only can have one Hybrid Automatic Repeat request (HARQ), for example, one Bit of feedback which is ACK or NACK. Even if one TB is divided into multiple Code Blocks (CBs) to be sent, the HARQ feedback is still one Bit, and as a result, when a TB is divided into multiple CBs to be sent, even if only one CB is falsely transmitted, the HARQ feedback would be NACK, and the entire TB would need to be retransmitted, which has low efficiency.

DETAILED DESCRIPTION OF EMBODIMENTS

A clear and complete description of the technical solutions of the embodiments of the present disclosure is given below, in conjunction with the accompanying drawings. Apparently, the embodiments described below are part of, but not all of, the embodiments of the present disclosure. All the other embodiments, obtained by a person skilled in the art on the basis of the embodiments described in the present disclosure without expenditure of creative labor, belong to the protection scope of the present disclosure.

In the present disclosure, the first device may in particular be a base station, although it may also be other types of devices, such as a smart terminal, in a practical application; the second device may in particular be a smart terminal, although it may also be a base station when the first device is a smart terminal. The embodiments of the present disclosure are not limited to the above-mentioned implementing forms of the first and second devices.

In New Radio (NR) technology, because multiple types of services such as enhanced Mobile BroadBand (eMBB) and Ultra-Reliable and Low Latency Communications (URLLC) need to be supported simultaneously, diversity multiplexing of the multiple types of services may be used. A phenomenon possibly caused by such diversity multiplexing is that, a first device allocates N Resource Blocks (RBs) of one Slot to eMBB UE#1, and the data and control signal corresponding to UE#1 are configured to be sent in Slot1 by the first device, however, in the middle of Slot1, a service of URLLC UE#2 suddenly arrived, and in order to meet the time-delay requirement for URLLC service, resource may be immediately allocated to URLLC UE#2, thus it is possible that part of symbols in the middle of Slot1 is then allocated to URLLC UE#2, that is to say, part of or all of the N Resource Blocks do not transmit the data and control signal of eMBB UE#1 in the duration of this part of symbols (as shown in FIG. 1, one CB in the middle is allocated to URLLC UE#2), but instead transmit the data and control signal of URLLC UE#2. In such situation, one TB of eMBB UE#1 would be divided into multiple CBs to be transmitted, but even if only one CB is falsely transmitted, one Bit of HARQ feedback which is NACK is still returned, and as a result, the entire TB would need to be retransmitted. This causes very low efficiency, because the TB of eMBB UE#1 is relatively large.

In order to increase efficiency, it is proposed to send HARQ feedback in a form of CB Groups, wherein the size of a CB Group is smaller than or equal to the size of a TB. In this way, when a TB is very large, it can be divided into a plurality of CB Groups for feedback, i.e., one Bit of HARQ feedback is configured for each CB Group, so that only those falsely transmitted CB Groups, with a feedback of NACK, need to be retransmitted, and it is not required to retransmit the entire TB. The NACK configuration of the above-mentioned one Bit of feedback may be that the value of 0 for the one Bit corresponds to NACK, and the value of 1 corresponds to ACK; or vice versa. The present disclosure is not limited to the above-mentioned specific values for ACK or NACK. In such situation, how to allocate the CB Groups and how to notify a user of the allocation manner of CB Groups remains a problem to be solved. Thus, the present disclosure provides an allocation method of Code Block Groups in a Transport Block to solve the problem about the allocation manner of CB Groups, so as to improve efficiency.

Referring to FIG. 2, FIG. 2 shows an allocation method of Code Block Groups in a Transport Block provided by the present application, which is implemented by a first device, the method as shown in FIG. 2 comprises the following steps:

Step S201, sending a TB through a first device to a second device, wherein, the TB comprises at least one CB Group which is obtained by the first device allocating the CBs in the TB according to a preset allocation strategy.

Optionally, the preset allocation strategy in the above-mentioned Step S201 may be any one of the following:

Strategy A: the first device divides all the CBs of a TB into X CB Groups, wherein, if the sum M of all the CBs is exactly divisible by X, the X CB Groups are allocated the same number of CBs; and if the sum M of all the CBs is not exactly divisible by X, L CBs are allocated to the first or last CB Group among the X CB Groups, and (M−L)/(X−1) CBs are allocated to the remaining CB Groups among the X CB Groups, where L is the remainder of M divided by X−1.

Herein, X=5 is taken as an example, if M=50, the 5 CB Groups are evenly allocated 10 CBs; if M=53, the remainder of M divided by 4 is 1, thus, 1 CB is allocated to the first CB Group, and 13 CBs are allocated to each of the remaining CB Groups. Of course, the configuration may also be that, 13 CBs are allocated to each of the first to fourth CB Groups, and 1 CB is allocated to the fifth CB Group.

The first device sends multiple candidate values of the X to the second device via a first signal, and sends the selected value of the X through the first device to the second device via a second signal; or the first device sends the selected value of the X to the second device via a first signal.

Strategy B: the first device divides all the Bits of a TB into one or more CB Groups, wherein, each of the CB Groups contains an integer number of CBs, and the sum of Bits of each of the CB Groups is less than or equal to Z.

Herein, 6 CBs in total are taken as an example, and for easy illustration, CB#1 CB#6 are used to refer to the 6 CBs, wherein, CB#1, CB#2, CB#3 are respectively 4800 bit, and CB#4, CB#5, CB#6 are respectively 4864 bit. Herein, Z may have a value of 10000 bit, and the allocation method may be that the first device allocates CB#1, CB#2 to CB Group1, because the sum of CB#1, CB#2 is 9600 bit and if CB#3 is further added, the sum would exceed 10000 bit, therefore, the first two CBs are allocated to CB Group1; for the same reason, CB#3, CB#4 are allocated to CB Group2, and CB#5, CB#6 are allocated to CB Group3. Each CB can only be allocated to one CB Group.

Optionally, the first device sends multiple candidate values of the Z to the second device via a first signal, and sends the selected value of the Z through the first device to the second device via a second signal; or the first device sends the selected value of the Z to the second device via a first signal.

Strategy C: if the sum M of all the CBs of a TB is exactly divisible by Y, the first device allocates Y CBs to each CB Group in the TB; if the sum M of all the CBs of a TB is not exactly divisible by Y, the first device allocates P CBs to the first or last CB Group in the TB, and allocates Y CBs to the remaining CB Groups in the TB, where P is the remainder of M divided by Y.

The above-mentioned X, Y, Z are positive integers.

Herein, Y=10 is taken as an example, if M=50, the first device allocates 10 CBs to each CB Group; if M=53, the first device allocates 10 CBs to each of the first five CB Groups, and allocates 3 CBs to the sixth CB Group; or, the first device allocates 3 CBs to the first CB Group, and allocates 10 CBs to each of the subsequent five CB Groups.

Optionally, the first device sends multiple candidate values of the Y to the second device via a first signal, and sends the selected value of the Y through the first device to the second device via a second signal; or the first device sends the selected value of the Y to the second device via the first signal.

The first signal mentioned above may be a Radio Resource Control (RRC) signal, the second signal mentioned above may be a Downlink Control Information (DCI) signal.

In the above-mentioned strategies, the value of X, Y, or Z may be a preset value stored in the second device.

It should be noted that, the above-mentioned method is used for allocation of CB Groups in an initially transmitted TB.

Optionally, the total number of CB Groups in a retransmitted TB equals the total number of unsuccessfully-received CB Groups in the initially transmitted TB.

If the retransmitted TB has multiple CB Groups, the number of CBs or Bits contained in the multiple CB Groups has the same allocation manner as the number of CBs or Bits contained in the corresponding unsuccessfully-received CB Groups in the initially transmitted TB. For example, the initially transmitted TB has 4 CB Groups, and the numbers of CBs of the 4 CB Groups are 4,4,4,3 in sequence. The allocation method of this initially transmitted TB may be implemented by Strategy A or Strategy C. If the first CB Group and the second CB Group are falsely received, the same numbers of CBs are used when retransmitting these two CB Groups, in this way, the user can determine the numbers of CBs contained in the retransmitted CB Groups because the same number of CBs are contained in each CB Group. Even if it is the first CB Group and the fourth CB Group that are falsely received and 7 CBs are contained in the retransmitted TB, the user can still determine that the first 4 CBs are retransmission of the first CB Group and the subsequent 3 CBs are retransmission of the fourth CB Group. Or for another example, if 5 CBs are contained in the retransmitted TB, the user can still determine that the first 3 CBs are retransmission of the first CB Group and the subsequent 2 CBs are retransmission of the fourth CB Group. The practical principle is that the same number of CBs are contained in each CB Group, and if the CBs cannot be divided evenly, the last CB Group (or the first CB Group) contains less CBs.

Step S202, sending the preset allocation strategy through the first device to the second device.

In the technical solution provided by the present disclosure, the CBs in a TB are allocated to obtain at least one CB Group, so that HARQ feedback based on CB Groups can be made, and retransmission based on basic units of CB Groups can also be performed, which may have the advantage of high efficiency.

Referring to FIG. 3, FIG. 3 shows an allocation method of Code Block Groups in a Transport Block provided by the present application, which is implemented by a first device, the method as shown in FIG. 3 comprises the following steps:

Step S301, sending a TB through a first device to a second device, wherein, the TB comprises X(5) CB Groups, and each of the CB Groups has 10 CBs.

Step S302, sending candidate values (4, 5, 6, 7) of X through the first device to the second device via a Radio Resource Control (RRC) signal, and sending a selected value 5 of the X through the first device to the second device via a Downlink Control Information (DCI) signal.

In the technical solution provided by the present disclosure, the CBs in a TB are allocated to obtain at least one CB Group, so that HARQ feedback based on CB Groups can be made, and retransmission based on basic units of CB Groups can also be performed, which may have the advantage of high efficiency.

Optionally, the Y value in Strategy C and the Z value in Strategy B can be handled in a similar manner referring to the handling manner of the X value as shown in FIG. 3.

Optionally, the preset allocation strategy is that a first device divides all the CBs of a TB into X CB Groups, wherein, if the sum M of all the CBs is exactly divisible by X, the X CB Groups are allocated the same number of CBs; and if the sum M of all the CBs is not exactly divisible by X, L CBs are allocated to the first or last CB Group among the X CB Groups, and (M−L)/(X−1) CBs are allocated to the remaining CB Groups among the X CB Groups, where L is the remainder of M divided by X−1.

Optionally, the preset allocation strategy is that a first device divides all the Bits of a TB into one or more CB Groups, wherein, each of the CB Groups contains an integer number of CBs, and the sum of Bits of each of the CB Groups is less than or equal to Z.
